b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.This method includes carbon dating and thermoluminescence.

century, science as a type of knowledge was more closely linked to philosophy.It is also important not to forget that throughout the history of humankind any discovery that shakes the status quo is always under attack until it becomes established, and we are in an era where many of the things that we once considered certain will become errors of our past.By John Black Dr John (Ioannis) Syrigos initially began writing on Ancient Origins under the pen name John Black.Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet.

Even though more than one method of verification is used in most cases, the lack of an accurate method to date non-organic materials lends a certain degree of uncertainty to the accepted history of our planet.

In the West, the term natural philosophy encompassed fields of study that are currently associated with science such as physics, astronomy, medicine, among many others.

centuries, scientists increasingly sought to formulate knowledge in terms of laws of nature.

The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.

The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.

This method is based on the fact that when a material is heated or exposed to sunlight, electrons are released and some of them are trapped inside the item.
